Confirming that his daughter remained under "medical supervision," Mitch Winehouse told BBC radio station 1Xtra that the singer, 24, spent a night in the hospital, where she was placed in a drip as a means "to rehydrate her after she'd been vomiting" as part of her treatment for drug addiction.
Amy Winehouse entered rehab on Jan. 24.
"Everything is going according to plan, and she's perfectly okay," Mitch Winehouse said, explaining that Amy was now out of the hospital and back in the rehab center.
The day she entered the facility, her rep said Winehouse "has come to understand that she requires specialist treatment to continue her ongoing recovery from drug addiction and prepare for her planned appearance at the Grammy Awards. She is nominated in an incredible six categories."
Her nominations include album of the year (Back to Black), song of the year and record of the year ("Rehab"), and best new artist.
